A factory needs to move packages from one level to another using a ramp. They want to choose a material that has a specific coefficient of friction with the packages that will be sliding down the ramp. What problem could occur if the coefficient of friction were too high? pur answer: Packages would go too fast and could break at the end of the ramp. Packages could slow down too quickly and stop before the end of the ramp. Packages could break the ramp because gravity would increase. Packages could bounce off the ramp because normal force would increase. Clear answer
